For what indications are antidepressants being used in adults in Colombia?

INTRODUCTION: Antidepressants are useful in the pharmacological treatment of different depressive and anxiety disorders, as well as being potentially useful in other indications. The aim of the study was to determine the indications for which antidepressants are being prescribed in patients over 18 years of age registered with the Colombian Health System. METHODS: Retrospective study with data from patients over 18 years old, of either sex, registered with the Colombian Health System, who are prescribed antidepressants. Medical records were reviewed, looking for indications approved and not approved by regulatory agencies. Patients were identified randomly, as well as the sociodemographic, clinical and pharmacological variables that could be associated with prescriptions for unapproved indications. RESULTS: 351 patients were evaluated, with a mean age of 60.4 ± 15.3 years, of whom 72.6% were women. They were attended in 34 cities, with prescriptions mainly by general practitioners (n = 276; 78.6%), and psychiatrists (n = 42; 12.0%). Selective serotonin reuptake inhibitors were the most widely prescribed antidepressants (n = 204; 58.1%), followed by atypicals (n = 76; 21.7%). The most frequent indications were for depression (n = 169; 48.1%), anxiety (n = 48; 13.7%), pain (n = 22; 6.3%) and sleep disorders (n = 17; 4.8%). A total of 188 prescriptions (53.6%) were made for approved indications, and the remaining 163 (46.4%) were classified as unapproved. CONCLUSIONS: Antidepressants are being prescribed for the treatment of depression, anxiety, pain and sleep disorders, especially in older adult women, but almost half of the formulations were for unapproved indications.

RESUMEN Introducción: Los antidepresivos son útiles en el tratamiento farmacológico de diferentes trastornos depresivos y de ansiedad, además de su potencial utilidad para otras indicaciones. El objetivo del estudio es determinar las indicaciones para las que se están prescribiendo los antidepresivos a pacientes mayores de 18 años afiliados al Sistema de Salud de Colombia. Métodos: Estudio retrospectivo con datos de pacientes mayores de 18 años, de cualquier sexo, afiliados al Sistema de Salud de Colombia, a los que se prescriben antidepresivos; se revisaron las historias clínicas buscando indicaciones aprobadas y no aprobadas por agencias reguladoras. Se identificó a los pacientes aleatoriamente, así como las variables sociodemográficas, clínicas y farmacológicas que se pudieran asociar con prescripciones para indicaciones no aprobadas. Resultados: Se evaluó a 351 pacientes, con una media de edad de 60,4 ± 15,3 años; el 72,6% eran mujeres; se atendieron en 34 ciudades, y los prescriptores principalmente fueron médico general (n = 276; 78,6%) y psiquiatra (n = 42; 12,0%). Los inhibidores selectivos de la recaptación de serotonina fueron los antidepresivos más prescritos (n = 204; 58,1%), seguidos de los atípicos (n = 76; 21,7%). Las indicaciones más frecuentes fueron depresión (n = 169; 48,1%), ansiedad (n = 48; 13,7%), dolor (n = 22; 6,3%) y trastornos del sueño (n = 17; 4,8%). Un total de 188 prescripciones (53,6%) se hicieron para indicaciones aprobadas y las 163 (46,4%) restantes se catalogaron como no aprobadas. Conclusiones: Los antidepresivos se están prescribiendo para tratar depresión, ansiedad, analgesia y trastornos del sueño, especialmente a mujeres adultas mayores, pero casi la mitad de las formulaciones fueron para indicaciones no aprobadas.

[Comparative assessment of off-label and unlicensed drug prescription in neonatal intensive care: FDA versus Brazilian guidelines]. / Evaluación comparativa de la prescripción off-label y unlicensed de fármacos en cuidados intensivos neonatales: Guías de la FDA versus guías brasileñas.

INTRODUCTION: Regulatory agencies are responsible for defining the use of off-label (OL) and unlicensed (UL) drug prescription in neonatal intensive care. However, these regulatory criteria may differ between agencies in different countries. The aim of this study was to establish the frequency of OL and UL drug prescription in a sample of patients in a neonatal intensive care unit applying the criteria of the Food and Drug Administration (FDA) of the United States and the Agência Nacional de Vigilância Sanitária (ANVISA) of Brazil, analysing the differences observed in the results based on the applied criteria. METHODS: Prospective cohort study in neonates admitted for more than 24hours to the neonatal intensive care unit (NICU) of a teaching maternity hospital between August 2017 and July 2018. We obtained information concerning the drugs included in the analysis of OL and UL prescriptions from the DrugDex-Micromedex® and official information on pharmaceutical products in Brazil. We used the kappa correlation coefficient to assess the agreement between the FDA and ANVISA criteria. We defined disagreement as a kappa value of less than 0.200. RESULTS: We evaluated 220 neonates admitted to the NICU and 17,421 items prescribed during the study period. We did not find a difference in the proportion of neonates in which at least 1 drug was prescribed under OL conditions applying the FDA versus the ANVISA criteria (96.4% vs. 98.6%). We found differences between the FDA and ANVISA in the OL classification based on the authorised age of use and indications for prescription, mainly in systemic antimicrobials and cardiovascular drugs. When we compared the prescribing information provided by the FDA and the ANVISA, we found that the criteria of the ANVISA were less specific. CONCLUSIONS: OL and UL drug prescription are frequent in neonatal intensive care applying the criteria of either agency, although the FDA has established more detailed criteria in terms of the ages and indications for which prescription is authorised.
